Description of the Invention: [Technical Field] The present invention relates to a support structure for a discharge tube, a support member, a discharge tube, a joint, a lighting device, a display device, and a television receiver. [Prior Art] Patent Document 1 discloses an example of a lighting device as a backlight function of a liquid crystal display device. The structure is such that: a metal part for connection is mounted on a substantially flat chassis, and a plurality of ends of the discharge member are mounted on the metal part for connection, and a power supply substrate is mounted on the metal part for connection The lead pin protrudes from the end portion of the discharge tube and is connected to the power source substrate via a connection metal member. [Patent Document 1] JP-A-2004-294592 [Technical Problem to be Solved by the Invention] Since the outer pin protrudes coaxially from the end portion of the discharge tube, the metal member for connection is applied to the shaft. When there is a positional deviation in the upward direction, there is a concern that the protruding end of the outer pin interferes with other members such as the peripheral wall of the chassis. The outer pin is important as an electrical connection mechanism, but it is preferable to avoid interference with other components because it is a thin and weak member. The present invention has been accomplished based on the above circumstances, and its purpose is to limit the movement of the discharge tube in the axial direction. [Technical Solution for Solving the Problem] As a means for achieving the above object, the support structure for a discharge tube of the present invention is 145591.doc 201018027, which is characterized in that it is provided by a support member disposed on a substantially flat plate The (4) branch of the glass tube is embedded with a plurality of discharge tubes in the form of a general shape, and is supported by at least one of the support members in the paired support, and is provided with a stopper for locking the foregoing The joint can restrict the movement of the discharge tube in the axial direction. According to the present invention, in the state in which the discharge tube is supported by the supporting member, since the joint is locked to the reading member, there is no possibility of placing (iv) the shaft of the supporting member. In the support structure of the discharge tube of the present invention, the discharge tube has a shape in which the outer 10 pin protrudes axially from the end portion of the glass tube, and protrudes from one side edge of the joint toward the outer lead side. The conductive sheet is connected to the outer lead, and the stop member may be disposed at a position that can be latched at an edge opposite to the conductive sheet on the joint. In this case, since the stopper is locked to the end edge of the joint, it is not necessary to form a hole for locking the stopper to the outer periphery of the joint, and the joint cost can be prevented while reducing the processing cost. Further, in the case where the stopper is locked to the end edge of the conductive sheet side of the joint, the conductive sheet extending from the joint end becomes obstructive due to the circumferential direction of the joint, and the joint end and the stopper are present. There is no doubt that the locking is not possible, but in the present invention, since the reading member is locked at the edge opposite to the conductive sheet, the joint and the stopper can be surely locked. In the above-described support structure for a discharge tube according to the present invention, a cylindrical portion in which the outer lead is connected over the entire circumference can be formed on the conductive sheet. i. The conductive sheet has a cylindrical shape in which the outer lead is surrounded by the entire circumference 145591.doc 201018027. Therefore, the conductive sheet is not detached from the outer lead, and the conductive sheet can be loosely connected to the outer lead. In the support structure for a discharge tube according to the present invention, the inner diameter of the joint is set to be larger than the outer diameter of the glass tube, and the elastic holding piece formed on the joint is brought into contact with the outer circumference of the glass tube, thereby enabling the aforementioned The joint remains substantially concentric with respect to the aforementioned glass tube. The locking margin of the joint and the stopper corresponds to the difference between the outer diameter of the glass tube and the outer diameter of the joint, but in the present invention, since the joint is held concentrically by the elastic retaining piece, it can be Increase the joint to ensure an increase in the difference between the inner diameter and the outer diameter of the glass tube. Thereby, the locking margin of the joint and the stopper can be increased, and the movement of the discharge tube can be surely restricted. In the support structure for a discharge tube according to the present invention, in the stopper, the recess is formed such that the outer periphery of the glass tube abuts or approaches in a state in which the joint is locked to the stopper. The member can be provided with an elastic pressing piece that can press the discharge tube toward the concave portion side. • In this case, since the elastic pressing piece can press the discharge tube toward the concave portion side, even if the depth of the concave portion is shallow, there is no possibility that the discharge tube is detached from the concave portion, and the joint can be surely locked to the stopper. The fact that the recess is shallow means that the size of the stopper in the depth direction of the recess is small, so that the material cost of the support member can be correspondingly reduced. In the support structure for a discharge tube according to the present invention, the support member is formed by assembling a metal member for connection into a holder made of a synthetic resin, and the stopper can be formed in the holder. In this case, since the stopper is formed in the synthetic resin holder, 145591.doc 201018027, it is not necessary to form the stopper on the metal part for connection, and the material required for manufacturing the metal part for connection can be correspondingly reduced. In view of the fact that the material cost of the synthetic resin is generally lower than that of the metal, according to the present invention, it is possible to reduce the material of the support member in the above-described support structure for the discharge tube of the present invention, and the support member is provided with a metal part for connection which can be electrically connected to the joint and which can be contacted. The stopper can be integrally formed with the aforementioned metal fitting for connection. In this case, since the metal fitting for connection with the conduction mechanism of the joint is integrally formed with the stopper, the present invention can be realized with fewer components than the stopper for providing the other component to the metal member for connection. Next, as a means for achieving the above object, the supporting member of the present invention is characterized in that it is provided on the front surface of the substantially flat plate-shaped chassis for supporting the fitting of the substantially cylindrical joint at the both ends of the glass tube. The plurality of discharge tubes of the form are provided with: (4) a stopper that can restrict the movement of the discharge tube in the axial direction by locking the joint. According to the present invention, the head is locked in the movement of the stopper. In the state in which the support member supports the discharge tube, there is no discharge tube for the support member to move toward the pomelo due to the connection

Therefore, it is not necessary to form a stop for the stop. Since the stopper is locked at the end of the joint, the hole of the outer circumference of the joint can be reduced, and the strength of the joint can be prevented from being reduced. Further, in the case where the stopper is locked to the end edge of the conductive sheet side of the joint, the conductive sheet extending from the joint end is inconvenient by the circumferential direction of the joint, and the joint end and the stop are present. The article cannot be locked, but in the present invention, since the stopper is locked to the edge on the opposite side to the conductive sheet, the joint and the stopper can be surely locked.

Press the elastic pressing piece. In this case, since the elastic pressing piece can press the discharge tube toward the concave portion side, even if the depth of the concave portion is shallow, there is no possibility that the discharge tube is detached from the concave portion, and the joint can be surely locked to the stopper. The fact that the recess is shallow means that the size of the recess 2 in the depth direction of the recess is small, so that the material cost of the support member can be correspondingly reduced. In the above-described support member of the present invention, a support member made of a synthetic resin and a metal member for connection incorporated in the support member are provided, and the stopper can be formed in the holder. In this case, since the stopper is formed in the support member made of synthetic resin, it is not necessary to form the stopper for the metal part for connection, and the material required for the metal part can be connected correspondingly. According to the present invention, the material of the support member can be lowered. 145591.doc 201018027 * The support member of the present invention described above is provided with a metal part for connection which can be electrically connected to the joint. The stopper can be integrally formed with the aforementioned metal fitting for connection. In this case, since the connection with the conduction mechanism of the joint is integrally formed by the metal member and the stopper, the present invention can be realized with fewer components than the stopper for providing the other component to the metal member for connection. Next, as a means for achieving the above object, the discharge tube of the present invention has a substantially cylindrical joint which is externally fitted to both end portions of the glass tube, and a support member provided on the front side of the substantially flat plate-shaped chassis. The supporter is characterized in that the joint can restrict the movement in the axial direction by locking the stopper to the stopper by the stopper provided on the support member. According to the present invention, in the state in which the discharge tube is supported by the support member, since the joint is locked to the stopper, there is no possibility that the discharge tube moves in the axial direction of the support member. In the above discharge tube of the present invention, the outer lead protrudes axially from the end portion of the glass tube, and the conductive sheet extending from one side edge of the joint to the outer side of the joint is connected to the outer lead. The end edge on the opposite side of the conductive sheet on the joint may be locked to the stopper. In this case, since the stopper is locked at the end edge of the joint, it is not necessary to form the hole for locking the stopper to the outer periphery of the joint, and the processing cost can be reduced, and the strength of the joint can be prevented from being lowered. Further, in the case where the stopper is locked to the end edge of the conductive sheet side of the joint, the conductive sheet 145591.doc -8 - 201018027 which protrudes from the joint end edge becomes obstructive by the circumferential direction of the joint. In the present invention, since the stopper end is locked to the end edge on the opposite side of the conductive sheet, the joint and the stopper can be surely locked. In the above discharge tube of the present invention, a cylindrical portion that is connected to the outer lead over the entire circumference can be formed on the conductive sheet. In this case, since the conductive sheet has a cylindrical portion that surrounds the outer lead all around, the conductive month is not detached from the outer lead, and the conductive sheet and the outer lead can be reliably connected. In the above discharge tube of the present invention, the inner diameter of the joint is set to be larger than the outer diameter of the glass tube, and the joint can be abutted by the elastic holding piece formed on the joint and the outer periphery of the glass tube. The aforementioned glass tubes are kept substantially concentric. The locking margin of the joint and the stopper corresponds to the difference in size between the outer diameter of the glass tube and the outer diameter of the joint. However, in the present invention, since the joint is placed concentrically with the glass tube by the elastic retaining piece, it can be increased by The large joint is read and the difference between the inner diameter and the outer diameter of the glass tube is increased. Thereby, the locking margin of the joint and the stopper can be increased, and the movement of the discharge tube can be surely restricted. Next, as a means for achieving the above object, the joint of the present invention constitutes a discharge tube supported by a support member on the front side of the substantially flat plate, and is externally embedded in the glass tube constituting the discharge tube. The tubular portion of the end portion is characterized in that it is possible to restrict the movement of the discharge tube in the axial direction by locking the stopper provided on the support member by locking the stopper. According to the present invention, in the state in which the discharge tube is supported by the supporting member, since the head is locked to the stopper member 145, there is no possibility that the discharge tube is axially moved to the supporting member. The joint of the present invention is configured as a joint of the discharge tube in such a manner that an outer lead protrudes axially from an end portion of the glass tube, and has a body 4 that is externally fitted to the glass member and is in the body One end edge of the conductive strip extending from the outer side of the outer side and connected to the outer lead, and the end edge 'on the side opposite to the conductive sheet of the main body can be locked with the stopper. Since the stopper is locked to the end edge of the joint body, it is not necessary to form a hole for locking the stopper to the outer circumference of the body, and the reduction in strength of the joint can be avoided while reducing the processing cost. Further, in the structure in which the stopper is locked to the end edge of the conductive sheet on the main body, the conductive sheet extending from the end edge of the body becomes inconvenient by the circumferential direction of the joint, and there is a body edge and The stopper cannot be locked, but in the present invention, since the stopper is locked to the end edge on the opposite side to the conductive sheet, the body and the stopper can be surely locked. In the above-described joint of the present invention, a cylindrical portion in which the outer lead is connected over the entire circumference can be formed on the conductive sheet. In this case, since the conductive sheet has the cylindrical portion that surrounds the outer lead all around, the conductive sheet is not detached from the outer lead, and the conductive sheet and the outer lead can be reliably connected. In the joint of the present invention, the inner diameter is set to be larger than the outer diameter of the glass tube, and has a cylindrical body that is externally fitted to the glass tube, and the elastic holding piece formed on the body and the glass tube is formed. The outer circumference can be kept substantially concentric with respect to the aforementioned glass tube. 14559l.doc 201018027 The locking margin of the joint and the stopper corresponds to the difference in size between the outer diameter of the glass tube and the outer diameter of the joint body, but in the present invention, since the body is kept concentric with the glass tube by the elastic retaining piece, Therefore, by increasing the main body, it is possible to ensure an increase in the difference in size between the inner diameter and the outer diameter of the glass tube. Thereby, the locking margin of the joint and the stopper can be increased, and the movement of the discharge tube can be surely restricted. Further, the illumination device for a display device of the present invention is characterized by comprising: a chassis, a supporting member of the present invention, a discharge tube of the present invention, and a power source provided on the back side of the chassis to supply electric power to the discharge tube.

At the avoidance opening 25, a stopper 26 is formed in such a manner that the opening edge thereof extends in a plate shape inwardly. With the stopper 26, the opening shape of the escape opening 25 is reduced to a substantially U-shape. The substantially U-shaped escape opening 25 is spaced apart from the upper and lower sides by a smaller inner diameter than the body 37 of the joint %, and is the same as or slightly larger than the outer diameter of the glass tube 34 of the discharge tube 15. The inner end of the opening edge of the avoidance opening 25 is a semi-circular recess, and the radius of curvature of the recess 27 is the same as or larger than the radius of curvature of the outer circumference of the glass tube 34.

Part. Mercury is sealed inside the glass tube 34, and both ends of the glass tube 34 are heated and melted to form a substantially hemispherical shape. Further, the outer lead 35 penetrates the hemispherical portion. The joint 36 is a single member formed by bending and tapping on a metal (for example, stainless steel) sheet which is punched into a specific shape. The joint 36 has one body 37 and one conductive sheet 4〇. The inner diameter of the cylindrical body 'body 37 which is integrally concentric with the glass tube 34 is set to be slightly larger than the outer diameter of the glass tube. The body 37' is formed by cutting a part thereof into a slit shape. The three pairs of elastic holding pieces 38A and 38B are arranged at equal angular intervals in the circumferential direction.

pieces 38A and 3, that is, elastically abut against the outer periphery of the glass tube 34, and as the assembly progresses, the contacts are slid to the outer peripheral surface of the glass tube 34. . Further, the outer end of the pin penetrating through the main body 37 starts to enter the hollow portion of the tubular portion 42. Thereafter, if the holding devices of the two sides reach a specific assembly position, the joint 36 and the glass tube 34 are positioned in the axial direction to the normal assembly position, and the front end of the outer lead 35 is surrounded by the circumference of the tubular portion. status. At this time, the front end portion of the outer lead 35 does not protrude greatly from the other end of the tubular portion 42, but is located at a position slightly protruding from the cylindrical portion 42 or substantially the same as the front end of the tubular portion 42, or located in the tube The interior of the portion 42. Thereafter, the tubular portion 42 is caulked by being reduced in diameter, and the tubular portion 42 and the outer lead 35 after the swaging are electrically fixed by welding, and the joint 36 and the glass tube 34 are integrated. With the above steps, the assembly is completed, and the discharge tube 15 is completed. In the state in which the joint 36 and the glass tube 34 are assembled, the main body 37 is substantially concentric with respect to the glass tube 34 by the elastic holding action of the three pairs of elastic holding pieces 38A, 38B, and is outside the glass tube 34 and the body 37. Zhou Zhi 145591.doc • 17- 201018027, to ensure that the gap (air layer) is generally reached throughout the week. Further, as shown in Figs. 22 and 23, the tubular portion 42 can be a U-shaped connecting portion 42a. In this case, after the glass tube 34 is embedded in the joint %, the U-shaped connecting portion 42a is bent along the outer lead 35, whereby the outer lead 35 is electrically connected to the connecting portion 42a. . According to the aspect in which the connecting portion 42a of such a shape is bent, the electrical connection to the outer lead 35 is further improved. [Installation of Discharge Tube 15 to Relay Connector 14] The discharge tube 15 manufactured as described above is mounted on the relay connector 14. At the time of mounting, the discharge tube 15 is horizontally oriented, and is brought close to the front surface of the chassis 13, and the both end portions of the glass tube 34 and the joint 36 are fitted to the valley chamber 23 of the relay connector 14 from the front side. At this time, the pair of elastic pressing pieces 32 are elastically flexed so as to be expanded upward and downward by the body 37 of the joint 36. After the main body 37 passes through the minimum interval of the pair of elastic pressing pieces 32, the two elastic pressing pieces 32 are used. The elastic restoring force pulls the body 37 into the inner side of the accommodating chamber 23, so that the body 37 abuts against the bottom of the chamber 23, thereby ending the installation of the discharge tube 15. The assembled discharge tube 15 is held by a pair of elastic holding pieces 32 at both end portions thereof, and is attached to the chassis 13 via the relay terminal 31 and the support member 20 which is the mounting body of the relay terminal 31. In this state, the weight of the discharge tube 15 acts on the chassis 13 only via the relay connector 14, and the weight of the discharge tube 15 does not have a load on the outer lead 35. Further, the pair of elastic pressing pieces 32 are elastically brought into contact with the outer peripheral surface of the body 37, whereby the outer lead 35 is electrically connected to the relay terminal 31 via the joint 36. Further, by the elastic restoring force of the pair of elastic pressing pieces 32, the glass tube 34 is held 145591.doc -18·201018027 in a state of being pressed by the concave portion 27 of the stopper 26, and is observed along the axial direction of the discharge tube 15. One of the bodies 37 is located at a position that coincides with the stopper 26. That is, a portion of the end edge on the opposite side to the conductive sheet 40 on the body 37 is in a state of being close to the axial direction and facing the stopper 26. Further, in the outer surface of the support member 20, at a right angle to the plate surface of the chassis 13, a surface such that a portion between the chassis 13 and the avoidance opening 25 is formed along the chassis 13 is formed outside the opening of the escape opening 25 of the storage chamber 23. Since the projecting portion 29 of the surface is protruded, the distance from the inside of the storage chamber 23 to the front surface of the chassis 13 becomes long. Thereby, leakage from the discharge tube 15 in the accommodating chamber 23 to the chassis 13 outside the holder 2 can be prevented. [Outline of Power Supply Substrate 16] The power supply substrate 16 includes a circuit board 17 on which a circuit is formed on the back surface (the surface opposite to the chassis 13), an electronic component 19 mounted on the back surface of the circuit board 17, and a plurality of circuits mounted on the back surface of the circuit board 17. Substrate connectors 18. The circuit board 17 is made of a paper base material phenolic resin laminated copper laminate (also referred to as paper phenolic) which is formed in a vertical rectangular shape as a whole. In the circuit board 17, a plurality of fitting holes 17H having a vertical rectangular shape are formed to penetrate from the front side to the back side. The plurality of fitting holes 17H are arranged in parallel with the side edges of the right and left sides of the circuit board 17 in correspondence with the relay terminal 31 (the relay connector 14). The substrate connector 18 is provided with a metal-made (for example, copper-nickel alloy) output terminal (not shown) that is housed in a synthetic resin and is housed in the outer casing, and is provided along the respective fitting holes 17H. The left and right edges of the circuit board 17 are arranged. One of the output terminals (not shown) corresponding to the fitting hole 7H is formed in the outer surface of the outer casing. 145591.doc • 19· 201018027 The power supply substrate 16 is assembled such that the circuit board 17 faces the chassis 13 in a direction parallel to the chassis 13 from the back side. At the time of assembly, the wall portion 22 of the relay connector 14 and the board connecting portion 33 disposed along the wall portion 22 penetrate the fitting hole 17H of the circuit board 7 and are inserted into the fitting recess 27 of the board connector 18. Thereby, the relay connector 14 is fitted to the board connector 18, and the relay terminal 31 and the output terminal are electrically connected to each other. [Function and Effect of the Embodiment] In the present embodiment, in the state in which the discharge tube 15 is supported by the relay connector 14, the connector 36 is locked to the stopper 26, so that the discharge tube 15 is not connected to the relay connector. 14 moves in the direction of drawing. That is, in the case where the moving force is applied to the discharge tube 5 in the right direction, since the joint 36 assembled to the left end portion of the discharge tube 15 is caught from the left side with respect to the stopper 26, the rightward side of the discharge tube 15 is restricted. mobile. In the case where the discharge force is applied to the discharge tube 15 to the left, since the joint 36 at the right end of the discharge tube 15 is locked to the stopper 26 from the right side, the movement of the discharge tube 15 to the left is restricted. Thus, since the discharge tube 15 is restricted in any direction in the left and right directions along its axis, there is no wall portion on the side opposite to the escape opening 25 in the front end of the outer lead 35 and the housing chamber 23. After touching. Moreover, since the stopper 26 is locked at the end edge of the joint 36, it is not necessary to form a hole for locking the stopper 26 to the outer circumference of the joint 36, and the strength of the joint 36 can be avoided while reducing the processing cost. reduce. Further, the clear shape of the end edge of the side of the conductive sheet 4 on the joint 36 of the stopper 26 is blocked by the circumferential direction of the joint 36, and the conductive sheet 40 which protrudes from the end edge of the joint % becomes inconvenient. There is a joint edge 36 and the stopper % cannot be 145591.doc •20· 201018027: the doubt is not satisfied 'but in the present embodiment gl' because the stopper % is locked at the edge of the opposite side of the conductive sheet 40, The joint 6% and the stopper 26 can be surely locked without being hindered by the conductive sheet buckle and the head 6" stopper 26 cannot be locked. Further, in the conductive sheet 40, since the outer lead 35 is formed over the entire circumference of the tubular portion 42', the conductive sheet 4G is not detached from the outer lead 35. Therefore, when the tubular portion 42 is swaged, the tubular portion 42 is not separated from the outer lead 35, and the conductive sheet 40 can be surely connected to the outer lead 35. Further, the locking margin of the joint 36 and the stopper 26 corresponds to the outer diameter of the glass tube 34 - and the size difference of the outer diameter of the joint 36. However, in the present embodiment, the joint 36 is held by the elastic holding pieces 38 Α, 38 Β. In order to make the glass tube 34 concentric, it is possible to ensure that the difference in size between the inner diameter and the external control of the glass tube 34 is increased by increasing the joint 36. Thereby, it is possible to increase the engagement margin of the joint 36 and the stopper 26 to surely restrict the movement of the discharge tube 15. Further, in the stopper 26, in a state where the joint 36 is locked to the stopper 26, a recess 27 is formed which abuts or approaches the outer circumference of the glass tube 34, and the discharge connector 14' is provided with a discharge tube 1 5, the pair of elastic pressing pieces 32' are pressed toward the concave portion 27 side. However, since the pair of elastic pressing pieces 32 press the discharge tube 15 to the concave portion 27 side symmetrically from obliquely upward and obliquely downward, the glass tube 34 does not have a After the recess 27 is detached, the joint 36 can be surely locked to the stopper 26. Further, the relay connector 14 is configured such that the relay terminal 31 is incorporated in the support member 20 made of synthetic resin. However, in the first embodiment, the stopper 26 is formed in the support member 2 made of synthetic resin. Therefore, it is not necessary to form a stopper on the relay terminal 145591.doc •21-201018027 31, and the material required for manufacturing the relay terminal 3i can be correspondingly reduced. In view of the fact that the material cost of the synthetic resin is generally lower than that of the metal, according to the present embodiment, the material cost of the relay connector 14 can be reduced. <Embodiment 2> Next, Embodiment 2 of the present invention will be described with reference to Figs. 15 to 21 . In the second embodiment, the mechanism for supporting the discharge tube 15 is different from the above-described embodiment. The other configurations are the same as those in the above-described embodiment 1, and the same components are denoted by the same reference numerals, and the description of the structure, operation, and effect thereof will be omitted. [Outline of the grounding member 50] In the first embodiment, the both ends of the discharge tube 15 are supported by the relay connector 14 including the holder 2 and the relay terminal 31. However, in the second embodiment, the discharge tube 15 is provided. One of the end portions of the both ends is supported by the relay connector 14 in the same manner as the embodiment, and the other end of the discharge tube 15 is provided by the grounding member 50 (the supporting member of the constituent elements of the present invention). stand by. The grounding member 50 is composed of an elongated supporting plate 51 attached to one side edge portion of the chassis 13, and a plurality of grounding terminals 52 (connection terminals of the constituent elements of the present invention) which are electrically connected to the front surface of the supporting plate 51. On the support plate 51, corresponding to each of the ground terminals 52, a mounting hole 51H of each of the three groups is formed through. Further, the support plate 51 is composed of a substrate and a metal plate. On the other hand, the ground terminal 52 is formed by bending a metal (for example, a copper-nickel-zinc alloy) plate material that has been pressed into a specific shape, and is configured to include a base portion 53 that protrudes from the upper and lower edges of the base portion 53 toward the front side. One of the upper and lower symmetry pairs of the elastic pressing piece 54 extends from the side edge portion of the base portion 53 toward the front side by a stopper 55 which is 145591.doc -22-201018027. The pair of elastic pressing pieces 54 are disposed on the side edge portion opposite to the stopper 55, and are formed in a curved shape by being expanded toward the opposite side of the elastic pressing piece 54 side. The elastic pressing piece 54 can be elastically flexed to expand the interval thereof, and the minimum interval of the elastic pressing piece 54 in the state of being not elastically deflected to the elastic pressing piece 54 is more than the outer diameter of the glass tube 34 of the discharge tube 15. Small size. The stopper 55 is erected at a right angle to the line of the discharge tube 15 from the base portion 53, and a recess 56 having a substantially arc-shaped recessed shape is formed in the stopper 55. In the relay connector 14 of the first embodiment, a pair of guide portions 28 are erected on the lower side of the recessed portion 27 of the stopper 26, but in the second embodiment, the upper and lower sides of the recessed portion 56 are erected from the base portion 53. The size control is small, and the mechanism corresponding to the guide portion 28 of the first embodiment is not provided. Therefore, the metal material required for the ground terminal 52 is smaller than that of the guide portion. Further, the three leg portions 57 are integrally formed at the base portion 53'. The two leg portions 57 of the three pieces are interposed between the elastic pressing piece 54 and the stopper 55, and protrude from the upper and lower edges of the base portion 53 toward the opposite side (back side) from the elastic pressing piece 54 and the stopper 55. The remaining one leg portion 57 protrudes from the intermediate position of the two elastic pressing pieces 54 located at the side edge of the base portion 53 opposite to the stopper 55 toward the opposite side (back side) from the elastic pressing piece 54 and the stopper 55. . The ground terminal 52 is not housed in a member such as a synthetic resin case, and the leg portion 57 is passed through the mounting hole 5 1H in a bare state, and the support plate 51 is electrically connected to the support plate 51 by welding or the like. Thereby, a plurality of ground terminals 52 mounted on one support plate 51 can be electrically connected to each other via the support plate 51. Further, the power supply substrate is not connected to the grounding member 50, and the support plate 51 is electrically connected to the chassis 145591.doc -23-201018027. [Installation of the discharge tube 15 to the ground terminal 52] When the discharge tube 15 is mounted on the ground terminal 52, the discharge tube 15 is brought close to the front surface of the chassis 13 in a horizontally oriented state, and the end portion of the glass tube 34 and the joint 36 are removed. The front side is fitted between the pair of upper and lower elastic pressing pieces 54. At this time, the pair of elastic pressing pieces 54 are elastically flexed by the main body 37 of the joint 36 to be elastically flexed. After the main body 37 passes through the minimum interval of the pair of elastic pressing pieces 54, the elastic pressing pieces 54 are elasticized by the elastic pressing piece 54. The restoring force pulls the main body 37 into the base portion 53 side, and the main body 37 abuts against the base portion 53, thereby completing the mounting of the discharge tube 15. Further, the end portion on the opposite side of the discharge tube 15 is attached to the relay connector 14 in the same manner as in the first embodiment. The mounted discharge tube 15 is supported at its both ends by a relay connector 14 and a grounding member 50. Since the pair of elastic pressing pieces 32, 54 elastically contact the outer peripheral surface of the body 37 of the joint 36, the outer lead 35 is electrically connected to the relay terminal 31 and the ground terminal 52 via the joint %. Further, the glass tube 34 is held in a state of being pressed by the recesses 27, 56 of the stoppers 26, 55 by the elastic restoring force of the pair of elastic pressing pieces 54, and the body 37 is viewed from the axial direction of the discharge tube 15, A portion of it is located at a position that coincides with the stoppers 26, 55. That is, a portion of the end edge on the side opposite to the conductive sheet 40 on the body 37 is in a state of being close to the axial direction and facing the stoppers 26, 55. Further, as shown in Figs. 24 and 25, a protective portion 551 may be provided to the ground terminal 52. When the protective portion 551 includes the elastic pressing piece regulating portion 552 and the support plate abutting portion 553', the grounding terminal 52 is attached to and fixed to the support plate 51, and the support plate abutting portion 553 is in contact with or close to the support plate 51. Further, in the case where some external force for expanding the elastic pressing piece 54 is applied to the elastic pressing piece 54, the elastic pressing piece regulating portion 552 is first abutted during the expanding process. Then, in the case where a larger load is added, the support plate abutting portion 553 plays a supporting role so that the protecting portion 55 1 does not fall. Further, the protecting portion 5 5 is connected from the root portion of the elastic pressing piece 5 4 , and in order to activate the supporting plate abutting portion 553 , the supporting plate abutting portion 5 5 3 must be formed outside the connecting portion. Further, by forming the support plate abutting portion 5 5 3 on the outer side, the effect can be further exhibited. [Function and Effect of the Embodiment] In the second embodiment, in the state in which the relay connector 14 and the grounding member 5 are supported by the discharge tube 15, the joints on both sides of the discharge tube 15 are stuck in the support member 20. The stopper 26 and the grounding terminal 52 are on the stopper 55, so that the discharge tube 15 does not move in the axial direction of the relay connector 14. That is, the slave relay connector 15 is provided with a slave relay connector! 4 In the case of the moving force of the side of the lateral grounding member 5, the stopper 36 assembled at the end of the relay connector 14 side of the discharge tube 15 is locked to the stopper 26 of the holder 2, and the discharge is restricted. The tube 15 is moved toward the side of the grounding member 5. In the case where the discharge tube 15 is given a moving force from the side of the grounding member 50 to the side of the connector 14, the stopper 36 at the end of the grounding member 50 side of the discharge tube 15 is locked to the stopper of the grounding terminal. 55, so the discharge tube 15 is restricted from moving to the side of the relay connector 4. In this way, since the discharge tube 15 is restricted in any direction in the left and right directions along its axis, the front end of the outer lead 35 and the side wall of the chassis 13 opposite the escape opening 25 in the storage chamber 23 are not touched. . Further, in the stopper 55 of the grounding terminal 52, in a state in which the joint 36 is locked to the stopper 55, a recess 145591.doc -25 - 201018027 56 ' is grounded so that the outer periphery of the glass tube 34 abuts or approaches. The terminal 52 is provided with a pair of elastic pressing pieces 54 that can press the discharge tube 5 toward the concave portion 56. However, the pair of elastic pressing pieces 54 vertically and obliquely align the discharge tube 15 toward the concave portion 56 from obliquely upward and obliquely downward. Since the side is pressed, the glass tube 34 is not detached from the recess 56, and the joint 36 can be surely locked to the stopper 55. Further, in the grounding member 50, the stopper 55 is integrally formed with the grounding terminal 52 for the conduction mechanism of the joint 36, so that in the second embodiment, fewer components can be used than the stopper for providing the other component to the grounding terminal. achieve.
